Carrying the ANSI and ISO designation 218.19-160T-04-M08, this insert features a positive rake geometry with a 10-degree rake angle and a 12-degree relief angle, promoting free-cutting action and reduced cutting forces. The F25M grade is coated with TiAlN and TiN via a PVD process, providing thermal resistance and wear protection across a range of workpiece materials. With three cutting edges and a T-Land cutting edge style, the insert balances edge strength with chip control. Licensed HVAC, machining, and tooling professionals specify this insert for its consistent performance in steel, stainless steel, and cast iron applications.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for use in milling operations across universal workpiece material classifications, with primary material codes H and P and secondary material codes P, M, and K covering steel, stainless steel, and cast iron. The M08 chip breaker geometry supports medium-grain material removal. It is compatible with the R218.19-32, R217.21-R160, and R220.21-R160 cutter series. Typical install scenarios include face milling, shoulder milling, and general-purpose milling on CNC machining centers in both production and maintenance shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction with TiAlN and TiN PVD coating for extended tool life\u003c\/li\u003e\n  \u003cli\u003eTrigon (triangle) insert shape with 60-degree included angle and three usable cutting edges\u003c\/li\u003e\n  \u003cli\u003ePositive rake angle of 10 degrees and 12-degree relief angle for reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eM08 chip breaker optimized for medium-grain steel, stainless steel, and cast iron\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 0.0790 inches with a corner radius of 0.0472 inches (3\/64 inch)\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation for flexible cutter mounting configurations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with the R218.19-32, R217.21-R160, and R220.21-R160 cutter series.

Always power down and lock out the machine spindle before seating or replacing inserts. Use the correct torx or hex key to secure the clamping screw to the tool body per the cutter body manufacturer specifications. Inspect the insert pocket and seating surface for chips or debris before installing a new insert to ensure proper seating and runout.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 218.19\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Trigon (Triangle)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Medium Grain\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: F25M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN and TiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI\/ISO Code\u003c\/strong\u003e: 218.19-160T-04-M08\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 160T-04\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: T-Land\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: M08\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 10 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 12 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0472 inches (3\/64 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1874 inches (3\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle Diameter\u003c\/strong\u003e: 0.4402 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1575 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.0790 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConvex Radius\u003c\/strong\u003e: 0.6299 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material Code\u003c\/strong\u003e: H, P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double Sided\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SECO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 74079736\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51557646860594,"sku":"74079736","price":375.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ccaa23473b7166911c76ea2d26bd4a29_d368677b-e37f-4421-a9ac-1371780dba70.jpg?v=1786391931","url":"https:\/\/voomisupply.com\/products\/seco-74079736-milling-insert-trigon-f25m-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
